Rumours were rife of a fallout between the two friends.
"Can you imagine, we're supposed to have fought over a legal problem that has cropped up over 'RA.One'. If we go by rumours then Shah Rukh and I have fallen out any number of times in the past few years, " said Mushtaq, a former journalist who appears in the second-half of "RA.One" as a gun-toting goon.
"It is my chance to intimidate Shah Rukh, something I can never do in real life. So I?m playing out a fantasy and loving it, " he added.
This is Mushtaq's third cameo in a Red Chillies production with Shah Rukh. He played similarly aggressive cameos in "Main Hoon Na" and "Om Shanti Om".
?I?ve very clearly told Shah Rukh when 'RA.One' becomes a blockbuster, I want my solo posters all over Bandra. He has agreed. But then Shah Rukh never says no to his friends, ? he said.
